"You're so warm inside me!" She screamed."Shhh... The others might hear." I said."That's okay, they're hung over-er-er-er" She kept bouncing on top of...my cock like she was riding a horse.He motion changed into a somehow angled motion. I could reach for her breast again. "Faster." I whispered. She kept thrusting fast and I raised my hips to go in deeper inside her wet pussy.Her hands crawled on to my shoulders and she held on tight as she squirted all over my legs. I let her fall sideways on the. I would lie there gazing at the sex and rubbing my young sensitive clit through my panties. My first orgasms were exhilarating, and I had multiple. My curiosity turned into addiction, and I spent every available opportunity sneaking a peak any erotic material I could get my hands on. And as soon as I could get my hands on that material, I got my hands on myself. My masturbation grew into rituals. Every time I bathed and without exception, before I slept. Soon, I invented reasons to be. With her sister no less. It all made my head spin and turned me on at the same time. The genes in her family were strong and my primal necessity to gather that genetic material and fuck it was now apparent. I was going to make my si ster-inlaw cum. I was going to fill her snatch tonight with all I had. she lowered her legs and I guided her on her knees and bent her over the sofa. I wanted to hit it doggy style and I wanted to hit it hard. she parted her legs slightly and giggled in. No more do I fear those midnight dreams of running down the school hall way in nothing but my underwear, but now a new fear and reality has set in. That of diapers strung on the line waiting to dry. Those very diapers that had been on my very bottom that were soiled by my very own waste. Yet all I could do was wait for another one to be wrapped around me.I bet your wondering why I'm so upset at my grandmother for what she did. You see after that first night things changed for the worst. That.
